BROOKLYN, new romp MUSICAL-DEVICE WIND-INDUCING APPARATUS.

Application filed January To all whom'it may concern: 4

Be it known-that I, Ronnn'r AGALLY, a citizen of the United States, residing at Brooklyn, New Yorlghave invented certain 5- new and useful lm prm ements in Musical- 'Device-find Inducing Apparatus, of .which the following is a. specification.

Theobjeet of my invention is the eonstruetion of a cheap, compact, simple, direct acting and easy working ztlu'l-ll-losfeffective wind-inducing'a paratus for iiiilsie:1l 1le\-'iees, it being cspeeia l useful for autimiatie instruments such as pian'o-ph'r yers and playerpia'nos, and particularlydesirable in the lat ter," where it leaves ample resonant space and easy sicmss" to-strings and trap work. In'tliedrawings' Figu're'lis a ront View of -a. player-piano with my apparatus, most of the front of the piano case being removed for' eleiinview; li igs. 1", 1" If", a-rennoditied forms of wind-chest, Fig.9.- is an nd viewof same instrument; while Figs. 3,4 and show larger endview-detailsof the' pumper pedals Fund supports.-

. 'l-l|e eommon form of bellows heretofore useibin'side of pianos. having an auto-plum- Jnatie action, has been the vertical, filling up thexlo'wer pilrt of the instrument to the injury of tone and the hindrance ol access for-repairs, besides having long, tortuous windways, and complicated mechanical con neetions for the foot poweraetion, both the latter eausing undue effort to overcome frietion in operation, and preventing the sensitive. control of air tension from the feet which is'requisite for artistic aeeenl and other expression.

In'my apparatus, as I adapt it to a player plane, I suspend. a horizontal wiml-chest'l 40 underneath and at the back of ,thekey-lwd'l of the piano and preferably attaehed by suspending means 3, '4, ap n-oximat-ely at each end so that no strain will be exerted to spring the lief-bed.

The wind-chest, may he redueed to a single '-b0ard.with channel grooved therein, Fig. 1, or the wind-chest inlay be integral with the key bottom, Fig. 1.", or the pumpers and reservoir be separate unitsconnected together by tubes or duets, Fig. 1", and yet anyor all be subject toelaimsherein, as my invention init-s broad sense relates to the general arrmigel'nent'of its three prineipal unite, the two feeders and the reservoir, and to the novel pedal structure.

6, 1908. Serial No. 409,473.

Underneath the keyboard, and preferably on the under face. of a wind-chest 1, are attaehed l-wo pumps 01' s0-called "ft-odors 5, (i, with their hinges at their ends hear to the ends of the wind-chest 1, their opening (worlv ing) ends, facing towards each other but at some distance apart, a. collapsible air-tension reservoir 7 being also suspended from. the wind-chest 1 intermediate the open ends of the .two pumpers.. The puinpers 5 and v6 and reservoir-7 each open directly into the wind-chest 1, said chest at its end connecting by a windwa'y upithrough kcybotttom 2 to an end-trunk S of the actions 9, thus supplying a. very direct. air-service to the note-striker pneumaties as 10, insuring a prompt, sympathetic control of expression. The arrangement of this form of bellows in combination with an auto-pneunmtie action in a. piano is not claimed herein, heing niade the subject of adivisional application hereof filed Mach. -1(ith,1908.-

The operation of the feeders 5, 6, by foot ower, is effected by pumpcr-pedals ll, 12-, having arms l3, 14 extending down therefrom preferably at or near their outer rear corners, with holes. at their lower ends into which the lmrerends of pumpe-r-rods 15; 16 are connected, the upper ends of these rods extending freely through holes in extensions .25, 26 at the. working ends of pumpers 5, 6, nuts on the ends of the rods providing afree working :1.lt-a.(-'l .nie-nt-.

The pum wrs .3, (5, are. preferably made of diagonal box form so that their moving hoards divide their action equally above and approximately straight pull from thevertieal rods 15;](3. Similarly, the arms l3, 14, are preferably of a length' that their holes engagingrods' l5, in, are. on a ltAGlWVlfill the hinge bearings of pl'nnper-iiedals 1, 12, when said pedals, arms and t'ods are half-way down their-stroke, thus securing an appr ximate straight pull on .the lower ends of the rods. With this straight-lino action and only two connecting centers, an exceedingly easy and noiseless foot operation is secured.

To hold the pedals 11, 12, in position foroperation as in Figs, 1,, 2, 3 and 4, and to ena )lO them to be moved inside of" the piano case when not in use, "as in'l ig. 5, e hase'or support 17 is used lorcarrying the hinges of the pedals 11, 1'3, this base 17 being carried by one or more swing arms-18 engaged to the below the horizontal plane. thus securing an base and having pivotal bearing inside the case on block 19. The pivotal bearing on 19 is preferably approximately in horizontal line with the connecting centers of arms 13, 14, and rods 15, 16 when the pedals ll, 12,

are at rest as in Fi s. l and 2, so that when the pedals with their arms,"and the base and swing-armsare all swung up and over' into the case the rods 15, 16-, will not cramp down or rise in the feeder extensions. a

To prevent undue forward pendulum movement, or jumping of the pedal arms 13, 14, over the ease rails 20, when pedals are swung into case, checks 21 are placed directly in front of and moderately clearing the arms when in action, but against which the lower ends of the arms will-bear .when the pedal parts are being moved into-or are at rest in the case. To revent the pedals from dro )ing too far w on swung into case, a chee )lOCk 22, or a similar device is placed to support the pedals, the rise of the checkat the rear preventing the pedals from ever juinping back against the strings of the piano.

Toenable the desirable advanced. position to the front of the rods 15, 16, and the swing-- ing well intofthe case of the pedals 11, 12 with their base 17 and swing arms 18, the

rods 15, 16 are preferably placed just outside of the outer edges of the pedals, the base is less in length than the distance between the rods 15, 16, and with swlng-arms 18 placed under each pedal :1 little inside of the arms [25, 14, the rods 15, 16 can hang quite close to the pedals 11,-,12.

'lhe'novelarrangement oi power-pneumatic 10 with its open end forward, a lever 13 fixed to'its moving board and extending to the rear of said board 'and reversing the downward stroke of the pneumatic to a dircet lift on thea-bstraet 24, is the most simple and ell'ective arrangement of these parts yet attained, and is especially desirable with this wind-hulnring apparatus, but not being clainnlble herein, same will be made the subject of i-lnim in a separate application. Such separate applieation has since been filed,
